This module extracts surface-consistent static correction values that are stored directly in the trace header geometry fields. Many seismic processing workflows write source and receiver elevation statics (or other pre-computed static shifts) into the geometry records attached to each trace. This module reads those values and produces a formal static correction dataset that can be applied to seismic data in subsequent processing steps.
For each trace in the input dataset, the module reads the static shift value stored on the source point and the static shift value stored on the receiver point. These per-point corrections are collected into a surface-consistent static corrections table, which assigns one static value to every unique source location and one static value to every unique receiver location. The result is immediately ready for use with static application modules.
Use this module when elevation statics, refraction statics, or other pre-calculated static values have been loaded into the geometry database and you want to extract them as a standalone static correction object — for example, before applying them, exporting them, or comparing them against statics computed by another method. This module has no user-adjustable parameters; it simply performs the extraction automatically.
The seismic trace dataset whose geometry records contain the static shift values to be extracted. Each trace must have valid source and receiver geometry points attached, and those geometry points must already carry the static shift values (for example, populated by a geometry loading or statics computation step earlier in the workflow). The module reads only the geometry fields and does not modify the trace samples or any other header values.
A surface-consistent static corrections table containing one static value per unique source location and one static value per unique receiver location, extracted directly from the trace geometry records. This output can be connected to static application modules, written to disk, or compared with statics produced by other methods (such as refraction inversion or first-break picking).
This module has no user-adjustable parameters. The extraction is performed automatically based on the static shift fields stored in the source and receiver geometry points of the input traces.
